Here is my latest sock project. It is A Good Sock yarn in the Knitter's Guide to the Galaxy colorway. I casted this project on before I had to go to the grocery store and I knew I would be waiting in line. I had completed my Cabin Cove Cosmic socks and desparately needed simple sock knitting to take along. I casted on and worked 2 rows of ribbing before I left. In line, I managed to complete 2 more rows of ribbing, much to the chagrin of the man in front of me as his wife started asking me some knitting questions. It turned out, however, that I casted on 68 sts instead of my usual 64 sts. I used my new Knit Picks 2.5 mm 32" circular needles which I really like and plan to buy more. This sock fits my larger left foot okay, for my right foot, I am using 2.25 mm dpns in hopes of creating a slightly smaller sock.
I usually cast on with a k2 p2 long-tail style cast on for my socks. I do the regular long tail stitch for the knit sts and this purl cast on for the purl sts. I do not start with a slip knot, I just put the needle on top of the yarn (which is going across my left thumb and index finger) and twist, creating a starting loop. For my recently completed Asparagus Cable socks, I casted on according to how the sts would be worked, for instance k2 followed by p3. I previously used the long tail cast on for my socks, but I like the look of the k2 p2 cast on much better.
